18 September 202410:00 AM (CDT) Non-invasive imaging of soil-plant continuum processes, such as root and soil water distributions, can be used to optimize agricultural practices. This presentation will show the how in-situ time-lapse horizontal crosshole ground penetrating radar (GPR) and root images can be linked. Data collected for maize growing seasons at two minirhizotron facilities in Selhausen, Germany is used, where root development and GPR permittivity were monitored at six depths across different treatments and

Near Shore, Near Surface Marine Electromagnetism to Address Scientific and Industry Questions
16 September 20247:00 AM (CDT) There is an increasing need to develop new geophysical tools in near shore marine environments, particularly for the first tens of meter below the seafloor. This need concerns geophysical imaging for marine renewable energy or more generally for geological studies, and also for the detection and localization of ferrous and non-ferrous metallic debris (uxo, wrecks), the tracking of cable or pipelines, archeology, etc. Acoustic and seismic techniques do not always

The Intersection of Water Quality, Public Policy, and Sustainability
SEG Women’s Network Committee International Women’s Day 2024 webinar
Spectral Decomposition Methods Comparison and Application in Fluvial Environment
Integrating Machine Learning Models for Predictive Analysis in Water Quality Assessment
10 June 20246:00 AM (CDT) The water quality project utilized the application of Python to analyze water quality datasets to assess potability. The datasets were obtained from the Kaggle data repository. The data obtained were various physical and chemical parameters associated with water quality such as pH, hardness, sulfate, chloramine, etc. The objective is to predict water potability, make informed decisions about water treatment processes, and ensure compliance with water quality standards. Machine learning techniques
Geophysical Monitoring of Permafrost
12 June 202410:00 AM (CDT) As the climate warms rapidly in the North, permafrost thaw is affecting infrastructure, landscapes, ecosystems, and carbon fluxes. Geophysical methods like electrical resistivity tomography (ERT) can be used to characterize permafrost conditions at the site scale and evaluate changes over time. This presentation will discuss recent advances in geophysical monitoring of permafrost, including time-lapse ERT datasets collected in northern Canada, the implementation of automated ERT systems, and the recent initiation
SEG Hydrogeophysics Webinar: So You Want to be a Practicing Near-Surface Geophysicist?
15 May 202410:00 AM (CDT) If you are studying and either love near-surface geophysics or think you could learn to love it and be paid for the privilege and want to pursue it as a career, you have two main choices. Both are admirable and rewarding choices, but this talk is about what it is like to be a practicing geophysicist, providing geophysical services, in government and particularly in a consulting environment. The world needs
Geophysical Response in Lithium-Brine Monitoring, New Exploration Paradigms and Sustainable Green Lithium
20 May 20247:00 AM (CDT) The energy transition drives the energy sector to renewable energy and electrification, being the critical minerals key players in the industrial development map. They comprise rare earth elements and 35 other elements including lithium that holds the ~65% of its world reserves in the so-called lithium triangle located in Argentina-Bolivia-Chile. The low electrical resistivities, variations in salt concentrations, weak acoustic impedances contrasts, and dynamics of the hydrogeological system, makes brine
